A reciprocal blade lapping machine ( 20 ) is taught that is used for sharpening cutting and shearing blades. The lapping machine consists a convex lap plate ( 32 ) mounted on an enclosure ( 22 ) rotated by an electric motor ( 34 ) connected to a speed reducer ( 36 ). A lapping compound distribution system is positioned directly above the lap plate and disperses lapping compound ( 64 ) onto the convex upper surface ( 48 ) of the lap plate providing an abrasive media for removing parent material from a set of blades placed on the lap plate. A conditioning ring ( 66 ), including dead weigh within, is rotatably disposed on the lap plate impacting directly upon the rotating lap plate maintaining the convex contour. A pair of reciprocating work piece holders ( 74 ) slideably rest on the lap plate, and alternately slide work pieces ( 76 ) backward and forward in a straight line on the rotating lap plate upper surface. Matched set of work pieces ( 76 ) are retained by the work piece hold downs ( 98 ) located within the work piece holders against the convex surface of the rotating lap plate, for sharpening by honing the mating cutting faces of the work pieces.
